One of the buzziest documentaries coming out of the 2017 Sundance Film Festival , Peter Bratt ‘s Dolores premiered Friday just in time for the doc’s inspirational subject, civil and labor rights leader Dolores Huerta , to speak at events surrounding the Park City Women’s March. Executive produced by legendary musician Carlos Santana , alongside consulting producer Benjamin Bratt , Dolores tells the story of Dolores Huerta, who bucked 1950s gender conventions by co-founding the country’s first farmworkers’ union.
